Check Digit Verification of cas no
The CAS Registry Mumber 284471-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,4,7 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 284471-68:
(8*2)+(7*8)+(6*4)+(5*4)+(4*7)+(3*1)+(2*6)+(1*8)=167
167 % 10 = 7
So 284471-68-7 is a valid CAS Registry Number.

Total synthesis of (+)-prelaureatin and (+)-laurallene
Crimmins, Michael T.,Tabet, Elie A.
, p. 5473 - 5476 (2007/10/03)
The first total syntheses of (+)-prelaureatin and (+)-laurallene are described. An asymmetric glycolate aldol addition was followed by a ring- closing metathesis to close the eight-membered ring allowing construction of the oxocene core of (+)-prelaureati
